You will get the results after the second stage of tests is done. These tests are done to find out the chance that your baby has a birth defect. These tests are done between 10 and 13 weeks of pregnancy. This test is done between 15 and 22 weeks of pregnancy. If your screening results are "positive," it doesn't prove that your baby has a birth defect. But it does mean that your baby is more likely to have a birth defect.
In that case, your doctor may want you to have another test to make sure. That test is called a diagnostic test. If the screening results are "negative," it means that your baby is less likely to have a birth defect. But it doesn't guarantee that you will have a normal pregnancy or a baby without birth defects.

Results from either a CVS or amniocentesis will tell whether the baby has a chromosome abnormality such as Down syndrome.
For women having an amniocentesis because of an increased risk of Down syndrome or trisomy 18, if a rapid lab test is done, results are available in three days. If an analysis of all chromosomes is done, results take about two weeks. If the pregnancy is found to carry a chromosome abnormality, a woman has the option to continue or end the pregnancy.
There is no benefit in doing more than one screening test. NIPT studies the DNA coming from the placenta into the maternal blood and uses different technology to analyze the results.
So having results from different screens can be confusing and misleading to you and your health care provider. However, if you chose FTS or NIPT as a screen, open neural tube defects will be looked for at the time of your detailed ultrasound weeks gestation.

In BC, IPS is performed as a sequential test: this means that the NT is performed at 12 weeks, and if the NT is large, the patient is offered amniocentesis or CVS, or they can wait for the rest of the blood work later in the pregnancy. However, it is very hard not to disclose the results of the ultrasound to a patient without a lot of patient anxiety.
For this reason, combined IPS is not popular. FTS is widely offered.
